In this study, we propose a novel anisotropy modeling of the polarization dependent meta-atoms at terahertz frequencies. The proposed anisotropic metamaterials are composed of metallic microstructures combined with various numbers of Hshaped meta-atoms. We confirm that the proposed metamaterials successfully realize the unique properties that can modulate the resonance frequency for the specific polarization of an incident wave, while can keep one identical resonance frequency for its orthogonal polarization direction, simultaneously. Moreover, regardless of the number of Hshaped meta-atoms, their bandwidth can be kept identical by coupling effects between adjacent meta-atoms and their excited electric dipole moments.
